Usage

HTML

Add the container element where NHN Cloud TOAST UI Chart will be created.

<div id="chart"></div>

JavaScript

Load

The NHN Cloud TOAST UI Chart can be used by creating an instance with the constructor function. To access the constructor function, import the module using one of the three following methods depending on your environment.

/* namespace */
const Chart = toastui.Chart;

/* CommonJS in Node.js */
const Chart = require('@toast-ui/chart');

/* ES6 in Node.js */
import Chart from '@toast-ui/chart';
import { BarChart } from '@toast-ui/chart';

In Webpack 4, when importing package modules, the parts that are defined in the module field have higher priority than the parts defined in the main field. To use the Webpack 4 with the require syntax to import @toast-ui/chart, the ESM file defined in the module field will be loaded, and the file will be transpiled to be compatible with the require syntax. In order to use the bundle file for UMD, the user must personally load and use the @toast-ui/chart/dist/toastui-chart.js or @toast-ui/chart/dist/toastui-chart.min.js.

const Chart = require('@toast-ui/chart/dist/toastui-chart.min.js'); // loading the bundle file for UMD

Webpack 5 supports the exports field. The entry point can be determined by the exports field defined in the package. Furthermore, the necessary chart can be loaded through a sub-path, as presented below.

const Chart = require('@toast-ui/chart'); // ./dist/toastui-chart.js

import { BarChart } from '@toast-ui/chart'; // ./dist/esm/index.js

import BarChart from '@toast-ui/chart/bar';
import ColumnChart from '@toast-ui/chart/column';
import LineChart from '@toast-ui/chart/line';
import AreaChart from '@toast-ui/chart/area';
import LineAreaChart from '@toast-ui/chart/lineArea';
import ColumnLineChart from '@toast-ui/chart/columnLine';
import BulletChart from '@toast-ui/chart/bullet';
import BoxPlotChart from '@toast-ui/chart/boxPlot';
import TreemapChart from '@toast-ui/chart/treemap';
import HeatmapChart from '@toast-ui/chart/heatmap';
import ScatterChart from '@toast-ui/chart/scatter';
import LineScatterChart from '@toast-ui/chart/lineScatter';
import BubbleChart from '@toast-ui/chart/bubble';
import PieChart from '@toast-ui/chart/pie';
import NestedPieChart from '@toast-ui/chart/nestedPie';
import RadarChart from '@toast-ui/chart/radar';

CSS

You need to add the CSS files needed for the Chart. Import CSS files in node environment, and add it to html file when using CDN.

  • ES6 Modules
import '@toast-ui/chart/dist/toastui-chart.min.css';
  • Common JS
require('@toast-ui/chart/dist/toastui-chart.min.css');
  • CDN
<link rel="stylesheet" href="https://uicdn.toast.com/chart/latest/toastui-chart.min.css" />

Creating Instance

Constructor function needs three parameters: el, data, options

  • el: Wrapper HTML element that will contain the chart as a child.
  • data: Numerical data the chart will be based on.
  • options: Functional options including legend, alignment, and tooltip formatter.
const el = document.getElementById('chart');
const data = {
  categories: ['Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
  series: [
    {
      name: 'Budget',
      data: [5000, 3000, 5000, 7000, 6000, 4000, 1000],
    },
    {
      name: 'Income',
      data: [8000, 4000, 7000, 2000, 6000, 3000, 5000],
    },
  ],
};
const options = {
  chart: { width: 700, height: 400 },
};

const chart = Chart.barChart({ el, data, options });
// const chart = new BarChart({ el, data, options }); // Second way
